The big find happened on March 6 at Crater of Diamonds State Park in Murfreesboro on the western edge of Arkansas where they advertise park policy on diamonds is "finders, keepers."

The inspiration to go diamond hunting came from Kalenda's mother-in-law who saw the Duggar family do it in an episode of TLC's "19 Kids and Counting."

The park noted this was the fourth diamond larger than a carat found just since mid-February. The park's interpreter released a statement saying workers plowed their diamond search field just in the last couple of months, and a recent rain washed diamonds so they caught sunlight especially well.

Kalenda told park workers he'll keep the rock. No word yet on how much it's worth.
